Torch roller mill

The present invention relates to a grinding device, and more particularly to a torch roller mill. Background technique

There are many types of roll pulverizers available, for example, there are many records in the Chinese patent literature. The existing roller mills have different structures, but their grinding rollers are generally suspended or horizontally mounted on the turntable. Generally, the structure is complicated, the space is large, and the grinding efficiency is low. Shortcomings such as short service life, in addition, not only low grinding efficiency, high energy consumption, but also difficult to repair, the replacement of parts is quite troublesome. Summary of the invention

In view of the defects existing in the prior roller pulverizer, the present invention provides a torch mill with high grinding efficiency, compact structure, low energy consumption, long service life, simple maintenance, and safe and reliable operation.

The torch roll mill provided by the invention comprises a box body with a soundproof cover and a cylindrical block sandwich structure, and the top of the box body is provided with a feed port and a fine powder discharge communicating with the inner cavity of the box interlayer The bottom of the box body is provided with a coarse powder discharge port communicating with the inner cavity of the box interlayer, the upper end of the main shaft installed in the box body is placed on the upper bearing seat, and the lower end of the main shaft is placed on the lower bearing seat. The bearing housing is fixedly mounted on the upper end surface of the casing, and the lower bearing seat is fixedly mounted on the lower bottom surface of the casing; the lower end of the lower bearing housing of the main shaft is coaxially fitted with a transmission wheel; between the upper bearing housing and the lower bearing housing At least two layers of the turntable and the equalizing tray are axially spaced on the main shaft; the periphery of the turntable is uniformly embedded with a plurality of, for example, at least three sliders rotatable with the main shaft, and the slider is hingedly mounted along the housing The inner wall surrounds the grinding roller, and the grinding roller is a torch-shaped grinding roller (referred to as a "torch roller") having a torch shape, and the inner wall portion corresponding to the torch-shaped grinding roller is equipped with a torch-shaped roller body. Shaped lining.

The torch-shaped grinding roller comprises a roller shaft, the upper end of the roller shaft is fixed with a roller sleeve, the roller sleeve has an inverted truncated cone shape, and the shape is like a flame of a torch, and the roller sleeve is a wear-resistant medium; the lower end sleeve of the roller shaft a bearing sleeve with a hinged ear, a bearing between the bearing sleeve and the roller shaft; The handle of the torch, the hinged ear on the bearing sleeve is connected to the slider mounted on the turntable through the pin. During operation, the material enters from the feed inlet at the top of the tank and is scattered onto the rotating uniform tray. The rotating uniform tray evenly spreads the material to the inner periphery of the box and falls between the torch-shaped grinding roller and the inner liner. After the grinding and pulverizing of the torch-shaped grinding roller and the inner lining, the qualified finished fine powder is sucked out by the peripheral fan from the fine powder discharging port at the top of the box interlayer, and is sent to the peripheral collecting device, and the set fineness is not reached. The required coarse-grained powder is discharged from the coarse material discharge port and sent to the peripheral lifting mechanism to be fed into the feed port to continue the circulating grinding.

The torch roller mill of the invention has flexible operation, low energy consumption, high grinding efficiency, long service life, convenient maintenance, convenient replacement of wearing parts, low running cost, can withstand frequent vibrations and large axial force, and low noise. Less iron consumption. DRAWINGS

In order to further clarify the gist of the present invention, the specific embodiments of the present invention will be described and illustrated in detail with reference to the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a schematic view showing the structure of a torch mill according to an embodiment of the present invention.

Fig. 2 is an enlarged schematic view showing the structure of a torch-shaped grinding roller in the torch mill of the embodiment shown in Fig. 1. detailed description

The present invention is further described in detail with reference to the accompanying drawings and embodiments, in which

According to an embodiment, referring to Fig. 1, a torch mill of the present invention comprises a casing 4 having a cylindrical split sandwich structure with a soundproof cover 13, the top of which is provided with a feed opening 11 and a fine powder discharge port 12 communicating with the inner cavity of the casing interlayer, and a bottom portion of the casing 4 is provided with a coarse powder discharge port 14 communicating with the inner cavity of the casing interlayer, and the upper end of the main shaft 1 installed in the casing 4 is disposed. On the upper bearing housing 10, the lower end of the main shaft 1 is placed on the lower bearing housing 3, the upper bearing housing 10 is fixedly mounted on the upper end surface of the housing 4, and the lower bearing housing 3 is fixedly mounted on the lower bottom surface of the housing 4; The lower end of the lower bearing housing 3 of the main shaft 1 is coaxially fitted with a transmission wheel 2; the main shaft 1 between the upper bearing housing 10 and the lower bearing housing 3 is axially spaced apart from the two-stage turntable 7 and the equalizing tray 9; The periphery of the turntable 7 is evenly embedded with four sliders 5 rotatable with the main shaft 1. The slider 5 is hinged with a grinding roller 6 which can be milled around the inner wall of the casing 4. The grinding roller 6 has a shape Torch-shaped torch-shaped grinding roller, the inner wall portion corresponding to the torch-shaped grinding roller 6 is mounted with the shape of the torch-shaped grinding roller 6 Adapted lining 8.

Referring to Fig. 2, the torch-shaped grinding roller 6 includes a roller shaft 62. The upper end of the roller shaft 62 is fixed to the roller sleeve 61. The roller sleeve 61 has an inverted truncated cone shape and is shaped like a torch flame. The roller sleeve 61 is resistant. Grinding medium; the lower end of the roller shaft 62 is sleeved with a bearing sleeve 64 with a hinged lug 63, and a bearing 65 is arranged between the bearing sleeve 64 and the roller shaft 62; the roller shaft 62 is shaped like a torch handle, and the bearing sleeve 64 is The hinge ear 63 is connected to the slider 5 mounted on the turntable 7 via a pin.

During operation, the material falls from the feed port 11 at the top of the tank 4 to the uniform feed tray 9, and the feed tray 9 spreads the material evenly. After multiple grinding by the torch-shaped grinding roller 6, the finished product is milled. The fine powder is sucked out from the discharge port 12 at the top of the sandwich of the box 4 by the peripheral exhaust fan to the peripheral collecting device, and the coarse powder that does not reach the set fineness is discharged from the coarse material discharging port 14 and sent into The peripheral lifting mechanism continues to input the feed port 11 for cyclic grinding.

The slider 5 provided by the torch mill of the present invention can ensure that the torch-shaped grinding roller 6 does not tilt outward and can move radially during operation, thereby compensating for the wear generated during the grinding process; for example, in the material to be ground Incorporating impurities such as iron lump that cannot be pulverized, since the torch-shaped grinding roller 6 can move radially, the torch-shaped grinding roller 6 can be prevented from being damaged, and thus can withstand frequent vibration and large axial force.
